"My grandmother, she bought me a bunch of Legos when I was kid so that just started the ball rolling," he said.

Last year, he entered a rubber band youth inventors contest.

"I was having a brain block. So, I couldn't think of anything and then I read an article about a woman in our neighborhood who had left her child in a car, so I thought maybe I could make something with the rubber bands to help that situation," Schuler said.

"You take the EZ Baby Saver and, as your getting in your car seat, you attach it to the door handle like so. When you're getting out of the car you see oh you know this bright flashing rubber band you're like oh you know my child is still in the car," Schuler explained.

Schuler won $500, bought a computer, then made a website.

Recently a judge sent a Smyrna woman to jail for leaving her two children in a hot car. Shortly after, Schuler's website went viral, generating thousands of hits and shares on Facebook and thousands of other hits on his website.

"It was something crazy like 26,000 and there were people from all over the world people from Germany, Australia, even people in Japan looking at it," Schuler said.

It's just rubber bands and duct tape.

"Instead of using gray, if you had a brighter color then you would notice it more," Schuler said

It's designed to save lives.

"It could happen to anyone," he said.

Schuler said he's not in it for the fortune and fame.

"I don't really care about having the publicity."

He posted directions on his website so others can make their own.

"I didn't make it where people had to pay for it and they could just make it themselves and it would just kind of raise awareness and it would make society a better place," Schuler said.

A Brentwood father of three recently created a smartphone app designed to fight the same problem. The app determines when the car has stopped moving for more than three minutes. An alert then goes to the phone asking "Did you remember the kids?" You can find the app on iTunes for $1.99.
